This book can be used when talking about maps. It incorporates latitude and longitude. The book contains exercises and can be used in centers.

This is a short, introductory book about latitude and longitude. I like how simple and straightforward it is, but I personally wish it was longer with more depth/detail. I would recommend it for younger kids just being introduced to the topic.

Very, very basic. Probably a little too basic for my oldest, but it is what it is. It definitely benefits from some hands-on activity with a map or globe alongside.
